In an earlier entry, I blogged about how users of non-geniune software secure their systems, and mentioned about IDC's analyst reporting the link between malicious/trojan software and non-geniune software. It seems that the connection is becoming stronger ever, and has grown beyond the Windows platform. 
 
According to Computerworld, "Trojan hides in pirated copies of Apple iWork '09" as well. As such, any software that can be exploited will be exploited.  Be aware, or beware.
